Hi all

I have a problem on how do osm save changes if two elements related to each other. As a case with a node included in a way, if there is a change made to that node, will the way also change? (both version numbers will change?)

Thanks for help.

If you move a node, or add tags to a node, and the node is part of a way, then the way will not change - the way will still be "last modified 2 years ago" even if - due to the changed location of the member node - the way will have looked totally different on the map yesterday.

The same is true for modifying a node or way or relation which are part of a relation - the parent relation will not change.

so that can I say the change made on each type of element is "isolated", in other words, the changes on different types elements are exclusive to each other?

@Digma: Yes. You only change what you (helped by your editor) change. Have a look at one of your changesets and view the osmChange XML (link on bottom of each changeset page). Ways are just a list of nodes – see elements in our wiki.
